Go Further with Advanced JavaScript Spreadsheet Calculations and Formulas

Iterative calculations can help with finding solutions to certain calculations by running them over and over using the previous result. For example, you can perform what-if analysis with the CalcEngine.goalSeek function or find the future value of an investment at a certain month. 

Build advanced formulas using Spread's powerful calculation engine. SpreadJS supports over 500 functions. You can use A1 Notation, R1C1 Notation, or Relative/Absolute referencing.

The INDIRECT function returns the reference specified by a text string. INDIRECT supports A1-style reference, R1C1-style reference, named reference, or a reference to a cell as a text string.

The dynamic array support is used to replace the array formula. Formulas with the potential to return multiple results refer to a dynamic array formula. Formulas currently returning many results are referred to as spilled array formulas.

SpreadJS provides localized calculation engine language packages that allow the user to enter formulas in their local languages. For example, 'SUM' will change to 'SOMME' in French.

SpreadJS supports the use of wildcards in functions “*” substitutes any number of characters, “?” represents/substitutes one character, and “~” identifies a literal question mark or asterisk character in the text string itself.

In addition to the 500+ built-in functions, the SpreadJS Calc Engine also allows you to create your own custom functions for specific business use cases. They can be defined and called as you would any of the built-in functions.

SpreadJS provides extensive support for formula auditing, allowing users to display relationships between formulas and cells by tracing the precedent and dependent cells in the worksheet.

Array formulas, often referred to as CSE (Ctrl+Shift+Enter) formulas, accept array arguments and return array values.

The AGGREGATE function supports 19 aggregate calculation and function options, including AVERAGE, COUNT, COUNTA, MAX, MIN, PRODUCT, SUM, VAR.S, VAR.P, MEDIAN, MODE.SNGL, LARGE, SMALL, PERCENTILE.INC., and more.

Use the built-in Excel-like filter dialog to allow your users to automatically filter their data or take advantage of creating custom filters to show and hide the relevant data as per your applications needs.

The RANDARRAY function returns an array of random numbers. Users can specify the number of rows and columns to fill, minimum and maximum values, and whether to return whole numbers or decimal values.

The SEQUENCE function generates a list of sequential numbers in an array, such as 1, 2, 3, 4.

The SORT function returns a sorted array of the elements in an array. The returned array is the same shape as the provided array argument.

The SORTBY function sorts the contents of a range or array based on the values in a corresponding range or array.

The UNIQUE function returns a list of unique values in a list or range. For example

=UNIQUE(array, by_col?, occurs_once?).

The intersection operator returns the value from an array that intersects with the cell using the operator.

Use the AsyncFunction to evaluate long-running asynchronous functions such as Web API calls to retrieve or update external data. You can also perform complex financial model calculations.

Give your users the ability to view and edit the formulas in your workbooks with a formula text box. Users can create formulas and select ranges to be referenced with the range selector button.
